Tangerang, Banten (ANTARA) – Indonesia’s Ministry of Energy and Mineral Resources (ESDM) is auctioning 13 new oil and gas blocks at the Indonesian Petroleum Association Convention and Exhibition (IPA Convex), which opened in Tangerang on Wednesday.“For those interested in participating, the auction begins today,” the ministry’s director general of oil and gas, Laode Sulaeman, remarked.The government is offering private and state-owned entities the flexibility to choose their preferred Production Sharing Contract (PSC) scheme, opting for either a gross split or a cost recovery model.Simply put, the gross split scheme allows companies to retain a larger portion of the production revenue, but without government reimbursement for production costs. Conversely, the cost recovery scheme allows companies to receive government reimbursement for production expenses, though the government's profit-sharing share is usually higher to offset those covered costs.Other incentives provided by the government include tax breaks and compensation for oil and gas deliveries under the Domestic Market Obligation (DMO), commonly known as the DMO Fee.For the direct offer route, access to bidding documents is open from May 20, 2026, to July 3, 2026, with the submission deadline set for July 6, 2026.Additionally, the government is opening a regular tender for the ABT 2025 study area, which includes the Rupat, Puri, Pesut Mahakam, Bengara II, Maratua II, Rombebai, and Jayapura working areas. In this category, bidding documents will be accessible from May 20, 2026, to July 17, 2026, with a submission deadline of July 20, 2026.Meanwhile, for the standard regular tender channels, the government is offering the Namori, South Tanimbar, Cerera, and Areca Bruni working areas.
